The stationary component has a correction surface that matches the side of the valve and is provided with a feed groove. The feed push rod is arranged in the feed groove to push the valve into the channel between the sliding component and the stationary component for correction. The valve correction device in the above document has the following shortcomings: directly correcting the valve that has not been heat treated is prone to large errors. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Embodiment 1:

[0028] A valve heat treatment correction device, such as Figure 1As shown, it includes a transmission mechanism, a heating box 10, and a correction mechanism 8. The transmission mechanism includes a plurality of transmission chain brackets 1. A transmission chain motor 2 is installed on the outer side of the upper part of the transmission chain bracket 1 through the bracket. The driving shaft of the transmission chain motor 2 is installed with a synchronous belt gear. A plurality of driving wheels 3 are rotatably installed on the inner side of the upper part of the transmission chain bracket 1 through a rotating shaft. A synchronous belt gear is installed at one end of the rotating shaft extending out of the outer side of the transmission chain bracket 1. Two transmission chains 4 are arranged in parallel on the surfaces of the plurality of driving wheels 3. The transmission chains 4 pass through the inside of the heating box 10. On the outer side of the transmission chain bracket 1, a plurality of synchronous belt gears are connected by a synchronous belt. A plurality of circular bases 25 are installed in a mirror image on the inner side of the two transmission chains 4. Loading elements 7 are rotatably installed on the plurality of circular bases 25.

[0029] By setting up a conveying mechanism, the valve can be automatically transported to a correction mechanism for correction after heat treatment of the valve, thereby effectively improving work efficiency.

[0030] The device is further configured such that the conveying chain 4 , the circular base 25 , and the loading element 7 are all made of high temperature resistant materials.

[0031] Through the solution, the transmission mechanism can carry the valve to undergo high-temperature heat treatment without being affected by the high temperature itself.

[0032] In order to solve the problem of automatic unloading; Figure 1 and Figure 4 As shown, every two loading elements 7 are arranged symmetrically and are arranged as a "convex" shaped structure with a narrow upper end and a wide lower end. A guide element 5 is installed above the correction mechanism 8, and a baffle 6 is installed on the upper end of the guide element 5. The baffle 6 is wider than the upper end of the "convex" shaped structure and narrower than the lower end.

[0033] According to the scheme, when the rotatable loading element moves forward with the valve, the loading element will tilt backward under the action of the blocking rod, so that the valve placed on the upper part falls due to gravity, thereby completing automatic unloading.

[0034] The device is further configured as follows: Figure 5 As shown, the lowermost end of the loading element 7 is inclined upward at 30 degrees.

[0035] Through the scheme, when the loading element carries the valve to move horizontally, the upwardly inclined head effectively prevents the valve from rolling off the loading element, causing damage to the valve and reducing work efficiency.

[0036] To solve the valve correction problem; such as Figure 2As shown, the correction mechanism 8 includes a base 11, on which two chassis 12 are installed, a hydraulic push rod 13 is installed on the inner wall of the left chassis 12, a pressure plate 14 is installed on the output end of the hydraulic push rod 13, and an anti-slip groove 15 is arranged on the surface of the pressure plate 14; a pressure roller is rotatably installed in the right chassis 12, and a pressure roller motor 18 is installed on the inner wall of the chassis 12 through a pressure roller motor bracket 17, and the output shaft of the pressure roller motor 18 is connected to the rotating shaft of the pressure roller 16.

[0037] By setting up a correction mechanism, the valves after heat treatment can be corrected. The hydraulic push rod can adjust the position of the pressure plate so that the mechanism can correct valves of different diameters. The anti-slip groove on the pressure plate effectively avoids changes in the valve posture during correction.

[0038] The device is further configured such that a detection mechanism 9 is installed on one side of the correction mechanism 8, and the detection mechanism 9 includes a detection workbench 19, and a detector 23 is slidably installed on the upper surface of the detection workbench 19 through a slide groove 24, and a claw disk motor 20 is installed on the upper surface of the detection workbench 19, and a claw disk 21 is rotatably installed on the claw disk motor 20, and a plurality of clamps 22 are installed on the claw disk 21.

[0039] By setting up the detection mechanism, the operator can easily perform straightness detection on the valve to confirm whether the valve is qualified, thereby improving work efficiency.

[0040] The device is further configured as follows: Figure 1 and Figure 4 As shown, a second guide element 26 is installed above the correction mechanism.

[0041] Through the scheme, when the valve falls from the loading element to the correction mechanism, under the action of the guide element 1 and the guide element 2, the valve will maintain the correct direction to avoid affecting the subsequent correction.

[0042] Working principle: The operator places the valve to be processed horizontally on the loading component 7. The conveyor chain motor 2 drives several driving wheels to rotate at the same linear speed through the synchronous belt, so that the two conveyor chains 4 and several loading components 7 arranged in mirror image move at the same speed. The loading component 7 carrying the valve is first heated to the specified temperature for heat treatment inside the heating box 10, and then the loading component 7 carries the valve to move in the direction of the correction mechanism 8. Because the stop rod 6 is wider than the upper part of the loading mold 7, the vertical loading component 7 is constantly tilted under the obstruction of the stop rod 6, causing the valve to move due to gravity. Falling; the falling valve falls between the pressure roller 16 and the pressure plate 14 in the correct direction under the action of the guide element 1 5 and the guide element 2 26, and the rotating pressure roller 16 driven by the pressure roller motor 18 applies pressure to the valve surface to complete the correction operation; the valve after correction falls to the base 11 and waits for cooling; the operator can install the cooled valve on the claw plate 21 through the clamping claw 22, and the claw plate 21 rotates slowly driven by the claw plate motor 20. At the same time, the detector 23 moves through the slide 24 to perform a straightness test on the rotating valve to ensure that the valve is qualified.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
